SMOKESTACK.

Application filed March 26, 1919.

To all whom it may concern:

Be it known that I, WILLIAM HAwKnR, a citizen of Canada, residing at Edmonton, Alberta, Canada, have invented certain new and useful Improvements in Smokestacks, of which the following is a specification.

This invention has for its object to provide a supplementary smoke stack for location in locomotive sheds and round houses capable of a relatively wide range of adjustment permitting it to be telescoped over the locomotive track and thus conduct the smoke and gases through the roof of the building.

Another object is the provision of a supplementary smoke stack capable of conducting the smoke from locomotives through the roof of a round house or other building embodying various novel adjustments permitting the stack to be moved laterally and longitudinally with relation to the locomotive track and thus expedite the application of the supplementary stack to the locomotive smoke stack.

Another object is to provide the supplementary stack with a hinged section which is automatically stripped by the upper terminal of the locomotive smoke stack when the locomotive is withdrawn from the supplementary stack thus preventing injury to the latter due to carelessness and neglect of the attendant to elevate the supplementary stack preliminary to the removal of the locomotive.

WVith these and other objects in view as will appear as the description proceeds, the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claims appended hereto. 7

In the drawings:

Figure 1 represents a fragmentary sectional view through the roof of a locomotive shed or round house illustrating the improved smoke stack applied thereto,

Fig. 2 represents an enlarged plan vlew, partly in section, of the stack,

Fig. 3 represents an enlarged side elevation partly broken away, and partly in section taken at right angles to Fig. 1., and

Fig. 4 represents a fragmentary plan view of the lateral adjustment for the stack.

Referring to the drawing in detail, where- Specification of Letters Patent.

Serial No. 285,258.

in similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the roof of a locomotive shed, round house or similar building structure provided with the usual supporting beams 6 which are utilized in the present invention to support the main longitudinal tracks 7 which are arranged above and parallel with the rails of the track and are supported by hangers 8.

A carrier truck designated generally by the numeral 9 is provided With flanged wheels 10 which travel upon the track rails 7 and the latter are preferably constructed of I-beams as is clearly evident by reference to Fig. 3, the flanges of the supporting Wheels 10 being so arranged as to prevent the truck from moving off the track. The truck consists of longitudinal and transverse members 11 and 12 respectively, which are bolted or otherwise rigidly connected and the transverse members are connected by the spaced stack supporting rods 13, the medial portions of which are oppositely bulged to accommodate the upper and relatively stationary stack section 14.

The roof 5 of the building structure is formed with an elongated slot receiving the upper stack section 14k and of a length approximately corresponding to the length of the track 7 so as to permit the truck 9 and supplementary stack to be moved from end to end of the track 7 and thereby facilitate application of the supplementary stack to locomotives located in various positions heneath the track structure shown.

A relatively long cover plate 15 is located beneath a slot in the roof 5 to prevent the admission of rain and the plate carries rollers 16 adapted to travel upon track rails 17 whereby the closure plate may be moved longitudinally with the stack section 14 during adjustment thereof. A supplementary adjusting plate 17 is mounted in guides 18 for movement transversely of the main closure plate 15 and the supplementary plate 17 is provided with the opening accommodating the stack section 'lt.

The opposite terminals of the truck or carrier 9 are provided with upstanding arms 19 having connection with the terminals of an adjustable cable 20, the medial portions of which are extended over guide pulleys 21 supported between the hangers 8 at the angular opposite terminals of the track 7 and the shaft supporting one of the pulleys is provided with a grooved wheel 22 supporting an adjusting chain or cable 23 having sufiicient slack to permit the chain or cable to hang within convenient reach from the floor and thuspermittingthe Wheel 22 tobe. conveniently rotated to produce the desired adjustment of the truck structure 9 longitudinally of the track 7.

The auxiliary longitudinal beams 13 constituting the support for the relatively stationary u-pper track section 14 form part of a movable carrier or support which also includes a platform 25 through which the track section 14 projects and supporting wheels 26 arranged to travel upon the transverse members 12 .of the frame structure of the main carrier truck 9. It is thus evident that by adjustment of the truck 9 longitudinally of the track rails 7 the desired adjustment of the supplementary track long1 tudinally'of the railway track may be ob I tained whereas by, proper adjustment of the supplementary carrier or support transversely of the frame of the main truck 9 the desiredlateral adjustment of the supplementary track with relation to the railway tracks may be obtained, the first adjustment being permitted by the longitudinalmovement of the closure plate 15 over the track rails 17 and the second adjustment being permitted by the transverse movement of the side plate 17 with relation to the main closure plate 15. 7

An angular depending bracket arm 27 is secured to the platform 25 of the supplementary carrier and pivotally support a rock shaft 28 carrying spaced parallel crank arms 29 connected by relatively short links 30 with the diametrically opposed trunnions 31 rigidly secured to the lower and vertically adjustable stack section 31. a

An arm 32 is rigidly attached to one terminal ofthe rock shaft 28 and carries at the terminal opposite the supplementary stack an adjustable weight 33 the arrangement of which is such as to depress the outer terminal of the arm and effect a corresponding upward movement of the arms 29 and vertically movable stack section 31 I A guide or track 34 is rigidly attached to the rock shaft 28 outwardly of the arm 32 and supports a grooved pulley 35 which is movable'longitudinally of the guide and is limited in its movement by the upturned terminal 36 of the guide. As clearly shown in Fig. 1, the guide 34- is secured centrally to the rock shaft 28 and projects laterally upon opposite sides thereof so that the pulley 35 travels from endto end of the guide and is located first upon oneside of the shaft and then upon the other. A

- counter-balance weight 37 is-suspended by a link 38 from the pulley 35 and when moved toward the weight 33, to the right of the pivotal axis of the arm 32, as in Fig. 1, the weights 33 and 37 .coact to elevate the arms 29 and the supplementary smoke stack. However, when the counter-balance weight is moved to the opposite terminal of the guideq34, its weight coacting with --the gravity actingupon and normally tending to lower the stack section 31 effects a downward movement of the latter and in case the smoke stack of the locomotive is prop-- erly located thereunder, the lower supplementary stack section telescopes therewith I and conducts'the smoke and gases through the roof of the building. For convenience in shifting the counter-balance weight 37 longitudinally of the guide 34, a cable 39 is secured centrally to the pulley 35, and extends over guide pulleys 40 located at" the opposite terminals of the guide and has its free ends extended below the terminals of the guide into convenient reach whereby to adjust the counter-balance weight longitudinally of the guide. 7 7 e The lower terminal of the vertically movable stacksection 31 is'fiared downwardly as at 41 for convenience in guiding it over the track of the locomotive and a section of the part 31 is cut out and'hingedly' secured as at 42 so as to be tilted out of its normal position by the lateral withdrawal of the locomotive smoke stack from position within the supplementary stack without injuring the latter. The top'edge of thehinged' section 43 is arranged to engage the inner surface of the main part of the stack section so as to limit the movement of the hinged section and maintain the latter in operative position. r

Angular straps 44 are fixedly secured to the frame structure of the supplementary truck or carrier'13 and are pivotally 'connected with horizontally disposed rods 44 which are attached at their outer terminals to depending crank arms 45 carried by the 110 rock shaft 46. The rock shaft 46 is jour naled in an angular supporting bracket 47 attached to the main carrier or truck structure 9 and is provided with diametrically opposed handles 48 extending horizontally from the shaft 46 and conveniently accessible for oscillating the shaft to produce a corresponding movementof the arms 45 and the desired lateral adjustment of the supplementary smoke tack through the connecting rods 44. y Y

The several truck wheels 10 and 26 are provided with angle guards 50 preventing the wheels from leaving their respective tracks and the terminal of the cover plate 125 15 extends over a gutter 51'by which rain water entering the slot 5 is conducted tov a suitable drainpipe (notshown).
